Abstract: A method for measuring a battery reserve capacity of a storage battery is applied to a battery detection device which is electrically connected to the storage battery by a Kelvin connector. The method includes: sending an input signal to a storage battery to control the discharging of the storage battery, and acquiring an output signal which is fed back, within an input duration of the input signal, by the storage battery regarding the input signal; determining a target battery parameter according to the output signal; acquiring a battery capacity table, wherein the battery capacity table includes a correlation between a battery parameter and a battery reserve capacity; and according to the battery capacity table and the target battery parameter, determining a battery reserve capacity corresponding to the target battery parameter. The measurement time for a battery reserve capacity of a storage battery is reduced, and the measurement efficiency is improved.

Abstract: A vehicle detection system includes a support, machine vision modules, a failure sensor, and a controller. Each machine vision module includes image acquisition devices each including s an image acquisition sensor for obtaining related parameters of hardware to be detected of a vehicle. The failure sensor is used for acquiring position change information of the image acquisition sensor and outputting a motion parameter signal comprising the position change information. The controller is used for determining, according to the motion parameter signal, whether the position of the image acquisition sensor needs to be calibrated. In the using process of the vehicle detection system, the controller can determine in real time whether the position of the image acquisition sensor needs to be calibrated, so as to avoid a miscorrection caused by detecting and correcting the vehicle without precalibration after the measurement and calculation precision of the vehicle detection system is reduced.

Abstract: Embodiments of the present invention relate to the field of automobile diagnosis technologies, and disclose a remote automobile diagnostic method and apparatus, a mobile terminal, an electronic device and a server. A controlled end of remote automobile diagnosis may automatically generate protocol data and send the protocol data to a controlling end; or the controlling end of the remote automobile diagnosis may parse the protocol data, generate an interface associated with a user interface of the controlled end, then receive an interface operation instruction, and generate action data according to the interface operation instruction and send the action data to the controlled end. In this way, a local diagnosis function is added to the controlling end, so that a remote diagnosis function is implemented accordingly, which has favorable scalability.

Abstract: A three-dimensional target, a wheel positioning system, and a wheel positioning method are provided. The three-dimensional target includes a base body. The base body is provided with at least three target surfaces which are all in different planes. Each of the at least three target surfaces is provided with target elements.
